Descrição geral

Iron(II,III) oxide, also known as ferric ferrous oxide, with a purity of 99.99% trace metals basis, exhibits unique magnetic, electrical, and catalytic properties. It has density of 4.8-5.1 g/mL at 25 °C and melting point of 1538 °C , which indicates thermal stability and mechanical strength. In the field of biomedical applications, it has shown promise in magnetic resonance imaging (MRI) contrast agents and drug delivery systems due to its magnetic properties and biocompatibility. In the semiconductor industry, iron(II,III) oxide has been investigated for its potential use in spintronics and magnetic tunnel junctions, where its magnetic properties can be utilized for information storage and processing. Additionally, it is being explored for use as an anode material in lithium-ion batteries, offering high theoretical capacity and low cost due to its abundance.

Magnetism and magnetic materials have been of scientific interest for over 1,000 years. More recently, fundamental investigations have focused on exploring the various types of magnetic materials and understanding the magnetic effects created by electric currents.

Magnetic materials permeate numerous daily activities in our lives. They are essential components of a diversity of products including hard drives that reliably store information on our computers, decorative magnets that keep the shopping list attached to the refrigerator door, electric bicycles that speed our commute to work, as well as wind turbines for conversion of wind energy to electrical power.
